POWERTRAIN MAINTENANCE
Access the powertrain by raising or removing the seat
and the truck bed. Some service procedures require the
vehicle to be lifted.
Refer to lifting the vehicle in the SAFETY section for
proper lifting procedure and safety information.
Checking the Oil Level
Do not overfill the engine. Too much
oil may cause the engine to smoke
or cause spark plug fouling.
NOTICE: Vehicles with the leaf springs mounted on
top of the rear axle will have an oil dipstick with an
H stamped into the top.
The oil level should be checked with the engine warm.
The vehicle should be on a level surface with the parking
brake engaged (Ref. Fig. 1). Allow adequate time for the
oil to drain into the crankcase before checking the oil.
1.
Clean the area around the oil fill cap.
2.
Remove the dipstick and wipe clean with a lint free
cloth.

3.
Insert the dipstick fully into the dipstick hole and
remove. Examine the level of the oil on the dipstick.
The engine can be operated safely as long as the oil level
is within the safe operating range as indicated on the dip
stick.
Oil should be added to bring the level into the safe operat-
ing range. Remember that oil expands as it gets hot. Do
not overfill (Ref. Fig. 2).
4.
Check that the oil cap is firmly in place.
5.
The oil dipstick/fill cap must be in place before oper-
ating the engine. Failure to install the dipstick/fill cap
will result in oil becoming contaminated and/or oil
being discharged into the engine compartment.
